Porsche 911 Speedster Backdate by dp Motorsport

THE Porsche tuner per se is dp motorsport with its operating main business in Overath, near Cologne. Already established in 1973 by Ekkehard ZIMMERMANN, nowadays, his son Patrick ZIMMERMANN and crew make sure that the renowned company’s name remains a resounding topic in the Porsche scene – of course, with the active support of the father.

A Berlin-based client – who priorly refurbished a 356 C-convertible almost by himself – assigned dp motorsport to “backdate” a Porsche 911 Speedster as it was perceived as “too modern”. Apparently, this particular Speedster already underwent a Phase 1; manufactured in 1989 in sunny US-American California, the original 911 Targa 3.2 converted, after meticulously detailed work in the late 1990s, into a Speedster. Subsequently, it made its way to Germany.

The Phase 2 upgrade at dp motorsport was implemented by applying the F-Model-Body kits dp11F Carrera-Widebody. Its combination of one inch wider wheel housings, a slightly lowered front bumper, as well as unobstrusively designed side sills that are truly captivating. A brilliant and thoughtful feature: these side sills cover the oil pipes in order to provide a more attractive trim at the bottom edge of the sills. By the way, the Overather expert team developed the design to achieve an even more sporty and vigorous appearance for the elderly 911. The vehicle height adjustment is handled via the shifting of the torsion bars and the usage of H&R spacer discs “improve” the wheels. The existing 2-pipe rear mufflers are visually adapted to the modified rear bumper. Because of the paint job in Nardo-gray, the already extremely flat 911 almost looks like a fighter jet.

For the next winter season dp motorsport is planning on a Phase 3 for the Speedster with the intention to install a – separately adjustable in height, compression and rebound – club sport thread chassis by KW. Additionally, PU-bearings by Superpro will be mounted to reduce the play in the axle bearings. The original 218 HP (= 160 kW) 3,2 l displacement with 5-gear-G50-transmission will gain a power upgrade to ca. 260 HP by using Schrick-camshafts, a bigger throttle valve, an exhaust manifold, as well as an individual adjustment on the engine test bench. The 7×16 inch rims with Continental Sport Contact tyres in 205/55-16 on the front axle and 9×16 with 245/45-16 on the rear axle are the perfect match. This Speedster is already a feast for the eyes. One may be excited about the final result after the next winter season…
